Biology 1060 Chapter 10 Photosynthesis

Significance of Photosynthesis Describe the importance of photosynthesis to the ecosystem Describe the structures of the leaf describe their contribution to photosynthesis and its aftermath Discuss the equation describeing photsynthesis Describe the role of each element Compare and contrast cellular respiration and photosynthesis

Stages of Photosynthesis Name the two stages of photosynthesis and the location of each Describe how these two stages are related Discuss the Calvin cycle and its products Relate it to the light-dependent reactions Define carbon fixation and photophosphorylation

Sunlight Describe the nature of light and the part that effects photosynthesis Discuss pigments and their role in photosynthesis Differentiate between spectrophotomers, absorption spectrum, electromagnetic spectrum, and action spectrum Discuss the role of accessory pigments

Excitation of Chlorophyll Discuss the relationships of ground and excited states of electrons and photon wavelength Describe the importance of the photosystem and its components to the light-dependent reactions Describe the two types of photosystems

Noncyclic Electron Flow Explain how noncyclic electron flow contributes to photsynthesis Describe the fate of an excited electron from PSII Describe the fate of an excited electron from PSI Describe where each electron comes from and goes to What its energy is used for How electron balance is restored

Cyclic Electron Flow Describe the process and effect of cyclic electron flow Compare and contrast noncyclic and cyclic electron flow Discuss the usefulness of each to the Calvin cycle

Chemiosmosis in Photosynthesis Compare and contrast chemiosmosis in mitochondria and chloroplasts Discuss the organization of molecules in the thylakoid membrane Discuss the associated components Summarize the light reactions of photosynthesis Scientific Inquiry p. 200

Calvin Cycle Summarize the Calvin cycle Describe the phases of the Calvin cycle, their reactants and products, and associated molecules Describe how glucose is produced by listing the numbers of each reactant and product, etc
